I have three of these 16 GB flash drives. I've been using one for a couple of years, I'm happy with everything. So I recently decided to buy two more. I checked them in Check Flash for 3.5 hours: there are no errors. The read and write speeds of both flash drives in the main and most intense part of the test are approximately the same and stable: 12.1-12.2 MB / s - reading and 2.9-3 MB / s - writing (see the screen at the end of the test). In HD Tune Pro, the average read speed of one of these flash drives is 12.0 MB/s. In principle, it is acceptable, it is important for me not to lose data, and not the speed at which they are copied and read. Therefore, for such little money, flash drives are very good in terms of reliability.
